Flights to one of Europe's best islands are on sale for $391 round-trip

Recently voted one of the best islands in Europe by Travel + Leisure readers, the Azores are celebrating their World’s Best Awards win with a 3-day flash sale to the beautiful archipelago.

Starting Tuesday, Azores Airlines is selling round-trip tickets for 33% off. The deal is available for travel between October 22 and December 12, with flights departing from Boston.

With this promotion, you have the flexibility to choose your dates and then apply the discount to your ticket, whether you book economy or business class. Round-trip tickets start at $391 (tax included) — but even if you’re not free to purchase the lowest price point, you will still save a lot, as full price tickets can run as high as $1000 round trip.

So what should you do when you get there? “There’s hiking, kayaking, canyoning, mountain biking, birding, whale watching — the list goes on,” Catarina Maia from Azores Getaways previously told T+L.

Head to São Miguel, the largest island in the archipelago, and consider hiking around the Caldeira das Sete Cidades, a caldera featuring stunning lakes and abundant vegetation. You could also go on a whale watching expedition in the Islet of Vila Franco do Campo, or get some R&R by soaking in a sulfurous hot spring at Ponta da Ferraria. For mesmerizing and unique views, make your way to Mosteiros Beach to watch the waves crash across the black lava rocks.

Be sure to see some of the other islands in the Azores while you’re there, too. Pico, nicknamed the “Island of Wine,” offers local wine tastings and wine tours, and Flores is a go-to destination for canyoning and scuba diving.

Fall temperatures in the Azores range in the high 60s to low 70s, so if you want to prolong warm weather as long as possible, the spring-like climes here are the perfect antidote to impending winter.
